Abstract

OMUNICAÇÃO DE DADOS DE MAGNITUDE DE PICO ASSOCIADOS A UM SINAL DE REFERÊNCIA PARA POSICIONAMENTO. Em uma modalidade, um primeiro nó (por exemplo, um UE ou uma BS) desempenha uma medição de resposta de canal em um sinal de referência para posicionamento (por exemplo, sinal de referência UL tal como SRS para posicionamento ou um DL PRS). O primeiro nó determina, para cada um de uma pluralidade de picos detectados dentro da medição de resposta de canal, informações específicas de pico compreendendo pelo menos dados de magnitude de pico que se baseiam em uma magnitude de pico relativa a um valor de referência. O primeiro nó reporta as informações específicas de pico para a pluralidade de picos para um segundo nó (por exemplo, uma BS, UE ou LMF). O segundo nó recebe as informações específicas de pico, e determina uma estimativa de posicionamento para um UE com base nas informações específicas de pico.COMMUNICATION OF PEAK MAGNITUDE DATA ASSOCIATED WITH A REFERENCE SIGNAL FOR POSITIONING. In one embodiment, a first node (e.g. a UE or a BS) performs a channel response measurement on a reference signal for positioning (e.g. UL reference signal such as SRS for positioning or a DL PRS). The first node determines, for each of a plurality of peaks detected within the channel response measurement, peak-specific information comprising at least peak magnitude data that is based on a peak magnitude relative to a reference value. The first node reports the peak-specific information for the plurality of peaks to a second node (e.g., a BS, UE, or LMF). The second node receives the peak specific information, and determines a positioning estimate for a UE based on the peak specific information.
